Subliminal Stimulation

The effect of subliminal and supraliminal accessory stimulation (white noise) on a visual detection task was determined through the use of the Theory of Signal Detection (SDT). Both the most extreme level of subliminal stimulation (–15 db) and the most extreme level of supraliminal stimulation (+15 db) resulted in the greatest increase in sensitivity ( d′) but neither had any effect on S's criteria (Beta).

Weak Activity

The review summarizes Kulikowski's contributions to the mechanisms involved in visual detection and discrimination. His findings provide strong evidence for the existence of ‘barriers’ which block weak activity in the visual system. It is proposed that the properties of these barriers may underlie near-optimal detection in conditions of signal uncertainty.
